Base 64 is an industry encoding method whose encoded characters
are determined by using a positional scheme that uses only ASCII characters.
Several Base 64 encoding schemes have been defined by the industry for specific
uses, such as e-mail or content masking. SAS maps positions 0-61 to
the characters A-Z, a-z, and 0-9. Position 62 maps to the
character +, and position 63 maps to the character /.
The following are some uses of Base 64 encoding:
The '=' character in the encoded results indicates that the results
have been padded with zero bits. In order for the encoded characters to be
decoded, the '=' must be included in the value to be decoded.
